-
FIG. 1 is a diagram showing anair conditioner 1 according to an exemplary embodiment. - The
air conditioner 1 heat-exchanges high temperature air with a low temperature refrigerant using a cooling cycle including a compressor, a condenser, an expansion valve, and an evaporator and then supplies low temperature air to the interior. Generally, the compressor and the condenser are disposed in an outdoor unit of the air conditioner, the expansion valve is disposed in any one of the indoor unit and the outdoor unit, and the evaporation is disposed in the indoor unit. - The indoor unit is divided into a stand type indoor unit standing on a floor in order to cool or heat a relatively large indoor space and a wall mounted type indoor unit mounted on a wall in order to cool or heat a relatively small indoor space.
- The wall mounted
type air conditioner 1 mounted on the wall includes a body provided with aninlet 3 and an outlet 5. The body includes a rear panel fixed to the wall and afront panel 10, alower panel 12, and a pair ofside panels 14 that enclose internal components such as a heat exchanger. - The inlet may be disposed at an upper portion of the
front panel 10. Theinlet 3 may be always opened or be opened by an operation of theair conditioner 1. Theinlet 3 may be provided with a filter device for removing foreign materials of air introduced from the interior into theair conditioner 1. - The outlet 5 may be positioned at a lower portion of the
front panel 10. The outlet 5 is a path through which the air introduced through theinlet 3 passes through the heat exchanger and is then discharged to the outside of theair conditioner 1. A blade 7 (SeeFIG. 2 ) may be installed on a front surface of the outlet 5 to control a direction in which the air is discharged. - As described above, the
air conditioner 1 according to an exemplary embodiment has a structure in which both of theinlet 3 and the outlet 5 are installed in thefront panel 10. An upper panel corresponding to thelower panel 12 is not present, and thefront panel 10 has one side contacting the wall to protrude so as to be convex with respect to the wall. Thefront panel 10 may include a first panel part provided with theinlet 3 and a second panel part connected to a lower portion of the first panel part and provided with the outlet 5. - The first and second panel parts of the
front panel 10 may be formed as a curved surface, and a portion at which the first and second panel parts are connected to each other may have a maximum spacing distance from the wall. One side of the first panel part may contact the wall and the other side thereof may be connected to the second panel part. One side of the second panel part may be connected to the first panel part and the other side thereof may be connected to thelower panel 12. The second panel part may be spaced apart from the wall so that thelower panel 12 may be positioned between the second panel part and the wall. - The pair of
side panels 14 may be installed on both sides of thefront panel 10 and thelower panel 12, respectively, to form the body of theair conditioner 1. Thefront panel 10 and the pair ofside panels 14 may be formed integrally with each other. The first and second panel parts may have acover 20 attached to front surfaces of upper portions thereof. Thecover 20 may be manufactured by double injection and form an appearance of theair conditioner 1. - The front surface of the second panel part may be provided with a
door 100 for opening and closing the outlet 5. Thedoor 100 may be connected to a lower portion of thecover 20 to cover the outlet 5 of the second panel part. Thecover 20 and thedoor 100 may have the same thickness so that theair conditioner 1 may have a smooth surface. Thedoor 100 may be manufactured by double injection, be attached to thefront panel 10, and form the appearance of theair conditioner 1. - In the case in which the
air conditioner 1 is not operated, thedoor 100 covers the outlet 5 and is connected to thecover 20, thereby making it possible to form a front surface of theair conditioner 1. Thedoor 100 completely covers the outlet 5, such that the outlet 5 may not be exposed to the outside. Therefore, theair conditioner 1 may be formed on the wall so that the front surface thereof formed by thecover 20 and thedoor 100 is exposed to the outside. - In the case in which the
air conditioner 1 is operated, thedoor 100 may be slid toward thelower panel 12 to expose the outlet 5 to the outside. Thedoor 100 may be slid along a curved movement trajectory to expose the outlet 5. In the case in which thedoor 100 is completely opened, a curvature of the movement trajectory may be changed so that the appearance of theair conditioner 1 seems to be slim. -
FIGS. 2 and 3 are diagrams showing a rear surface of theair conditioner 1 according to an exemplary embodiment, whereinFIG. 2 shows the case in which thedoor 100 is closed andFIG. 3 shows the case in which thedoor 100 is opened.

front panel 10 may be provided with drivingdevices 200 providing power so that thedoor 100 may be slid. The drivingdevices 200 may be disposed at both sides of an inner surface of thefront panel 10 so as to be adjacent to twoside panels 14. - Edges at which all of the
side panels 14, thefront panel 10, and thelower panel 12 abut together are provided withexternal openings 30, such that the moving drivingdevices 200 may be slid together with thedoor 100 through theexternal openings 30 to thereby be exposed to the outside. Both sides of thelower panel 12 may be depressed in order to form theexternal openings 30. - The
driving device 200 may be coupled to one side of thedoor 100 so as to be slid together with thedoor 100. Thedriving device 200 may slide thedoor 100 while moving to the outside of theair conditioner 1 through theexternal opening 30. When thedoor 100 is slid to move toward thelower panel 12, the installation member for installing the blade 7 and the blade 7 may be exposed. Conditioned air may be injected into the interior through the outlet 5 while the blade 7 is rotated. - The
door 100 may include side ribs 102 formed on both sides thereof, wherein the side ribs 120 protrude so as to contact the pair ofside panels 14. The pair ofside panels 14 may include side guides 104 concavely formed along the movement trajectory, respectively, so that thedoor 100 may be stably moved. The side ribs 102 of thedoor 100 may include protrusions protruding toward theside panels 14 so as to be fitted into the side guides 104 of theside panels 14, respectively. Thedoor 100 is slid in the state in which the protrusion is fitted into theside guide 104, thereby making it possible to prevent thedoor 100 from being separated by external force. - In order to prevent a phenomenon that a central portion of the
door 100 sags due to a weight of the door itself when thedoor 100 of which both sides are connected to the drivingdevices 200 is slid, an inner side of thedoor 100 may be provided with at least one sag preventing part 170. Thesag preventing part 107 may have a ‘T’ shaped cross section and be lengthily extended at an inner side of thedoor 100 in a direction in which thedoor 100 is slid. Aguide 105 may be installed at a lower portion of the outlet so that thesag preventing part 107 may be caught and thedoor 100 slid. Theguide 105 may be installed integrally with the installation member for installing the blade 7 or be installed separately from the installation member. Theguide 105 may be provided with at least one protrusion corresponding to thesag preventing part 107 so that thesag preventing part 107 may be caught. -
FIG. 4 is a diagram showing a side of theair conditioner 1 according to an exemplary embodiment. - An inner portion of the
air conditioner 1 is provided with aheat exchanger 16 performing heat exchange with air introduced from the interior to cool or heat the air. Theheat exchanger 16 serves as an evaporator at the time of a cooling operation and serves as a condenser at the time of a heating operation. A plurality ofheat exchangers 16 are disposed in theair conditioner 1 so as to effectively perform heat exchange with the air introduced from the interior. - A
cross-flow fan 18 may be positioned together with theheat exchanger 16 in the air conditioner. Thecross-flow fan 18 may forcibly circulate the air of the interior so that the introduced air is discharged to the interior through the outlet 5. Thecross-flow fan 18 may have a plurality of wings disposed in a radial direction and be coupled to a driving motor to thereby be rotated at a high speed. - The inner portion of the
air conditioner 1 may be provided with a filter removing dust included in the air sucked from the interior to clean the air and a drain tray draining condensation water generated on a surface of the heat exchanger at the time of the cooling operation to the outside. - When the
air conditioner 1 is operated, thecross-flow fan 18 is rotated at a high speed by the driving motor, such that the air of the interior is introduced into the air conditioner through theinlet 3 and is then heat-exchanged while passing through theheat exchanger 16. The air is again discharged to the indoor space through the outlet 5. Theair conditioner 1 circulates the air by the above-mentioned process to cool or heat the indoor space. - The
driving device 200 moving thedoor 100 opening and closing the outlet 5 may include apinion 40 that rotates and arack 45 engaged and moved with thepinion 40. Thedriving device 200 may include acase 32 forming an appearance so as to protect thepinion 40 and therack 45 positioned therein. Thecase 32 may be fixed to both sides of the inner surface of thefront panel 10. - The
rack 45 may have a form in which a sawtooth is attached to a bar formed in a length direction and bent as a curve. Therefore, therack 45 may be moved along a curved path depending on rotation of thepinion 40. - The
case 32 may include aninternal opening 33 formed at one side thereof so that therack 45 positioned in the fixedcase 32 may be exposed to the outside while moving. One side of therack 45 exposed through theinternal opening 33 may be connected to one side of thedoor 100. That is, one side of therack 45 and one side of thedoor 100 may be coupled to each other while having a lower portion of thefront panel 10 disposed therebetween. - As the
air conditioner 1 is operated, thepinion 40 may be rotated and therack 45 engaged with thepinion 40 may be moved. Therack 45 may pass through theinternal opening 33 to thereby exit from thecase 32, and pass through theexternal opening 30 provided in the body to thereby be exposed to the outside. Thedoor 100 having one side connected to therack 45 may be moved to a lower portion of thelower panel 12 while being slid together with therack 45 as therack 45 is moved. - One side of the
rack 45 and one side of thedoor 100 are coupled to each other, such that a space in which the lower portion of thefront panel 10 may be positioned may be formed between therack 45 and thedoor 100. Therefore, the lower portion of thefront panel 10 may be formed in a flat plate in which an opening or a coupling member for installing therack 45 is not present. In addition, one side of therack 45 and one side of thedoor 100 are connected to each other, such that thedoor 100 and therack 45 may have different curvatures. - Both sides of an inner surface of the
door 100 may be provided withprotrusions 47 protruding inwardly. Theprotrusion 47 may include a rib 49 extended toward theinternal opening 33 of thecase 32. Therack 45 and the rib 49 may be coupled to each other in a length direction of therack 45, and one side of therack 45 may be coupled to theprotrusion 47 while being fitted into theprotrusion 47. A screw may be inserted so as to penetrate through theprotrusion 47 and one side of therack 45 that are coupled to each other, thereby fixing theprotrusion 47 and one side of therack 45. In order to stably couple therack 45 and thedoor 100 to each other, therack 45 coupled to thedoor 100 may include a protrusion protruding downwardly so as to be fitted into thedoor 100. - Since one side of the
door 100 and one side of therack 45 are coupled to each other, in the case in which thedoor 100 is completely separated from thefront panel 10 to thereby be opened, a phenomenon that the other side of thedoor 100 that is not coupled to therack 45 sags due to a weight of the door itself may occur. Therefore, the rib 49 deeply inserted into therack 45 is provided to firmly couple therack 45 and thedoor 100 to each other and move the center of gravity of thedoor 100 toward the center of thedoor 100, thereby making it possible to prevent the phenomenon that thedoor 100 sags. - The
door 100 may be installed to be slid adjacently to thelower panel 12 in order for the entire volume of theair conditioner 1 to seem to be slim even in the state in which thedoor 100 is completely opened. To this end, a curvature of thedoor 100 may be larger than that of therack 45. Thedoor 100 may have the same curvature as that of thefront panel 10 and be attached to the front surface of thefront panel 10. As therack 45 is moved, thedoor 100 is slid while gradually moving according to the curvature of therack 45. That is, thedoor 100 may be slid along a movement trajectory changed from the curvature of thefront panel 10 to the curvature of therack 45. -
FIG. 5 is a diagram showing thedriving device 200 of theair conditioner 1 according to an exemplary embodiment. - The
driving device 200 may include amotor 35 providing power, thepinion 40 having a shaft connected to themotor 35 to thereby be rotated, therack 45 engaged and moved with thepinion 40, and thecase 32 enclosing themotor 35, thepinion 40, and therack 45. As described above, therack 45 has one side coupled to thedoor 100, such that it may be slid together with thedoor 100. - The
case 32 may include first andsecond cases rack 45, thepinion 40, and themotor 35 may be positioned therein. Thecase 32 may have a form in which it is bent in the length direction in accordance with a form of therack 45 and have a circular space formed at one side thereof so as to receive themotor 35 and thepinion 40. The first andsecond cases hook 34 and be fixed to a rear surface of thefront panel 10. - In the case in which the
door 100 is opened, thedoor 100 descends depending on a weight of the door itself. Therefore, a torque required in the case in which thedoor 100 is opened is less than a torque required in the case in which the door ascends against the weight of the door itself to thereby be closed. In the last 20 to 30% section in which thedoor 100 is closed, a torque larger than a maximum torque required to open thedoor 100 is required. - When the
driving device 200 is provided in accordance with the torque required in the last 20 to 30% section, a gear having a large reduction gear ratio needs to be used or a specification of themotor 35 needs to be high. In the case in which the reduction gear ratio is large, a driving speed is decreased, and in the case in which the motor having the high specification is used, efficiency is decreased in terms of a size and a cost. Therefore, it is efficient to satisfy the torque required in the last 20 to 30% section by finding a method of securing a torque margin. - As one method of securing the torque margin, there is a method of variably controlling the
motor 35. Themotor 35 may be a step motor rotated by a predetermined angle depending on input pulses. The step motor may be controlled by a pulse per second (PPS). In the last 20 to 30% section, the PSS is slightly slowly controlled, thereby making it possible to control a torque. For example, in the last 20 to 30% section, when a pulse speed is doubly increased to doubly slow the PPS, an additional torque may be obtained. -
FIG. 6 is a diagram showing thedriving device 200 of theair conditioner 1 according to an exemplary embodiment. - As another method of securing the torque margin, there is a method of installing an
auxiliary device 70 providing elastic force. Theauxiliary device 70 may be positioned together with therack 45 and thepinion 40 in thecase 32. Theauxiliary device 70 may include aspring 72 providing the elastic force and aconnection member 74 having one side connected to thespring 72 to thereby be moved. - The
auxiliary device 70 may be installed in the vicinity of the last 20 to 30% of an ascending section so as to provide the elastic force to therack 45. Thespring 72 may be fixed to aconnector 39 positioned at one side of thecase 32, and theconnection member 74 may be connected to a side of thespring 72 opposite to one side of thespring 72 fixed to theconnector 39. A side of theconnection member 74 opposite to the side of theconnection member 74 connected to thespring 72 may be coupled to therack 45 so that theconnection member 74 may be moved while expanding and contracting thespring 72 as therack 45 is moved. - Four sides of the
connection member 74 may have a similar plate shape, and one side thereof may be similar length to that of therack 45. Theconnection member 74 may have aconcave surface 78 formed at a central portion thereof so that therack 45 may be coupled thereto, and a lower portion of therack 45 may be convexly formed so as to correspond to theconcave surface 78, One side of therack 45 may be put on theconnection member 74, and the lower portion of therack 45 may be coupled to theconcave surface 78. A section in which therack 45 and theconnection member 74 are coupled to each other and are moved is called an interworking section. - Both sides of the
concave surface 78 may be provided with a plurality of protrusions 76 and 77 protruding outwardly. The protrusions 76 and 77 are formed so as to correspond to both sides of theconnection member 74, such that a total of four protrusions, that is, a pair of upper protrusions 77 and a pair of lower protrusions 76 may be formed. The pair of upper protrusions 77 and the pair of lower protrusions 76 may be fitted intoauxiliary guides 36 formed along a movement path of theconnection member 74 at both sides of thecase 34. - In the case in which the
door 100 is opened while therack 45 is moved to the outside, theconnection member 74 may also be moved downwardly along therack 45 fixed to theconcave surface 78. The upper and lower protrusions 77 and 76 are moved while being slid along the auxiliary guides 36, and thespring 72 connected to theconnection member 74 is expanded. One side of theauxiliary guide 36 may be provided with a bent fixing groove 37 so that theconnection member 74 is separated from therack 45 and is fixed in the state in which thespring 72 is expanded. - The
connection member 74 is inclined while the lower protrusion 76 of theconnection member 74 moved along therack 45 is fitted into the bent fixing groove 37. Therack 45 may be separated from theconcave surface 78 of theinclined connection member 74 and move thedoor 100 while being continuously moved downwardly. Theconnection member 74 may be fixed in the state in which the lower protrusion 76 is fitted into the fixing groove 37, and thespring 72 may be fixed in the state in which it is expanded by a movement distance of theconnection member 74. - In the case in which the
door 100 is closed, therack 45 may ascend while being again moved inwardly of thecase 32 and be again coupled to theconnection member 74 fixed to the vicinity of a start point of the interworking section. Theconnection member 74 that has been inclined may again return to the state in which it is not inclined while being coupled to therack 45, and the lower protrusion 76 may exit from the fixing groove 37. Thespring 72 starts to compress theconnection member 74 with elastic force with which it is to return to its original state, thereby making it possible to provide force to therack 45 through theconnection member 74 connected thereto to allow therack 45 to ascend. Therefore, in the interworking section, force of themotor 35 and the elastic force of thespring 72 are summed, such that therack 45 ascends to the end. As a result, thedoor 100 may be again attached to the front surface of thefront panel 10. -
FIG. 7 is a diagram showing a diagram showing thecase 32 of thedriving device 200 of theair conditioner 1 according to an exemplary embodiment. - For convenience, the
second case 32 b of thedriving device 200 has been shown inFIG. 7 , and the first andsecond cases second case 32 b may be coupled to thefirst case 32 a using thehook 34 to form a space in which theauxiliary device 70, therack 45, thepinion 40, and the like, may be positioned. One side of thesecond case 32 b may be provided with theinternal opening 33 so that therack 45 may be moved outwardly, and the other side thereof may be provided with theconnector 39 to which thespring 72 may be fixed. Theauxiliary guide 36 and the fixing groove 37 may be disposed in the interworking section in which theconnection member 74 of thesecond case 32 b is moved together with therack 45. - The
auxiliary guide 36 may be provided with asafety groove 80 into which the protrusions 76 and 77 may be inserted, in addition to the fixing groove 37. In the case in which therack 45 is moved downwardly to open thedoor 100, the lower protrusion 76 of theconnection member 74 is fitted into and fixed to the fixing groove 37. In this case, the lower protrusion 76 deviates from the fixing groove 37 due to external impact, such that theconnection member 74 may be moved upwardly by the elastic force of thespring 72. In this situation, when therack 45 is moved upwardly, it is difficult for therack 45 to be coupled to theconcave surface 78 of theconnection member 74 that is not inclined. Therefore, thesafety groove 80 is provided, such that the lower protrusion 76 is inserted into thesafety groove 80 and then returns to the fixing groove 37, thereby making it possible to couple therack 45 to theconcave surface 78. - An inner surface of the
case 32 b may be provided with aguide 38 concavely formed along a movement path of therack 45 so that therack 45 may be stably moved. Theguide 38 may be extended from one side of thecase 32 b to the other side of thecase 32 b along the movement path of therack 45. However, in this case, contact friction between therack 45 and theguide 38 may be increased. As the contact friction is increased, a larger torque may be required to move therack 45. Therefore, in order to decrease the contact friction, theguide 38 may be formed in a minimum section in which therack 45 may be stably moved along the movement path. -
FIG. 8A is a diagram showing a driving device andFIG. 8B is a diagram showing a cross section of thedriving device 200 of theair conditioner 1 according to an exemplary embodiment. - Even though the
guide 38 is formed in the minimum section, since a surface on which therack 45 and theguide 38 contact each other is large, the contact friction may be still present. Therack 45 may have an upper surface on which a sawtooth engaged with thepinion 40 is formed and both sides on which rackribs 46 movable along theguide 38 are formed. Therack rib 46 may be fitted into acontact surface 48 positioned on an inner surface of theguide 38 and be slid. - The
contact surface 48 may have a form in which it encloses upper and lower portions of therack rib 46 so that therack rib 46 does not deviate from theguide 38. Due to thecontact surface 48 contacting therack rib 46 in the form in which it encloses the upper and lower portions of therack rib 46, the contact friction may be increased. Therefore, in order to decrease the contact friction between therack rib 46 and thecontact surface 48, therack rib 46 may be inserted into thecontact surface 48 while having a gap. Therack rib 46 has a gradient larger than that of thecontact surface 48, such that therack rib 46 and thecontact surface 48 do not surface-contact each other, but may line-contact each other. An empty space is formed between therack rib 46 and thecontact surface 48 contacting each other, such that the contact friction may be decreased. - According to exemplary embodiments, a clean and smooth appearance may be formed using a door slid along a curved path and a slim appearance may be formed even in the state in which the door is opened.
- In addition, in a section in which additional power is required while the door ascends, a time required for driving the door may be decreased using a spring.
- Although specific shapes have been mainly described, they may be variously modified and altered by those skilled in the art. These modifications and alterations should be interpreted to fall within the scope of embodiments.
- Although a few embodiments have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
